Microsoft has released the first IE9 Platform Preview for Developers
A quote from the article:
>> First IE9 Platform Preview Available for Developers
| When we started looking deeply at HTML5, we saw that it will enable a new class of applications. These applications will stress the browser runtime and underlying hardware in ways today’s websites don’t. We quickly realized that doing HTML5 right – our intent from the start – is more about designing our browser’s subsystems around what these new applications will need than it is about a particular set of features. From the beginning, we approached IE9 with the goal of enabling professional-grade, modern HTML5 support on top of modern hardware through Windows.
At the MIX conference today, we demonstrated how the standard web patterns that developers already know and use broadly run better by taking advantage of PC hardware through IE9 on Windows. This blog post provides an overview of what we showed today, across performance, standards, hardware-accelerated HTML5 graphics, and the availability of the IE9 Platform Preview for developers. First, we showed IE9’s new script engine, internally known as “Chakra,” and the progress we’ve made on an industry benchmark for JavaScript performance. With the differences between script engines on benchmarks approaching the duration of an eye-blink, we described our approach for making real-world sites faster. Chakra compiles JavaScript in the background on a separate core of the CPU, parallel to IE. We showed our progress in making the same standards-based HTML, script, and formatting markup work across different browsers. We shared the data and framework that informed our approach, and demonstrated better support for several standards: HTML5, DOM, and CSS3. We showed IE9’s latest Acid3 score (55); as we make progress on the industry goal of having the same markup that developers actually use working across browsers, our Acid3 score will continue to go up. As part of our commitment to the standards process, we submitted test cases to the standards bodies. We also made these tests available for everyone to try in any browser. In several demonstrations, we showed the significant performance gains that graphically rich, interactive web pages enjoy when a browser takes full advantage of the PC’s hardware capabilities through the operating system. The same HTML, script, and CSS markup work across several different browsers; the pages just run significantly faster in IE9 because of hardware-accelerated graphics. IE9 is also the first browser to provide hardware-accelerated SVG support. Finally, we announced the availability of the first IE Platform Preview for developers, and our commitment to update it approximately every eight weeks. We want the developer community to have an earlier hands-on experience with the progress we’re making on the IE platform. The Platform Preview, and the feedback loop it is part of, marks a major change from previous IE releases. |
